Cisco Secure Access Activity Plotter

🚀 A blazing-fast visualization tool for large-scale CSV exports from Cisco Secure Access (Activity Search).

📌 Overview

This project simplifies the visualization of large firewall activity logs exported from Cisco Secure Access.
The raw CSV data can contain hundreds of thousands of entries — making manual graphing in Excel or Google Sheets impractical.
This Python-based tool enables fast, scalable, and customizable plotting of key activity trends.
